Threat to the WhatsApp platform instant messaging , is plagued by a flaw that allows messages to be manipulated ., and cybersecurity experts who have found a way to hack WhatsApp and manipulate messages have said that Facebook has failed to fix the flaws, one year after the social network was alerted.
Researchers at Check Point, a cybersecurity company, said they discovered new vulnerabilities in August last year in which a hacker could intercept and manipulate messages sent in private and group conversations.
This threat to WhatsApp platform allows attackers to create and disseminate misleading information from supposedly reliable sources.
The problems relate to using the quote function in a group conversation to change the identity of the sender, even if that person is not a member of the group, modify the text of someone else’s reply, and send a private message disguised as a public message to everyone to participate in another group, so that when the target person answers, his message is visible to everyone in conversation.
The cybersecurity company explained that WhatsApp, which Facebook bought in 2014, has failed to solve the problems that still exist today.
Speaking at the Black Hat Internet Security Conference, Oded Vanunu, head of product vulnerability research at the security company, said Facebook blamed WhatsApp’s flaws on restrictions that cannot be resolved because of the platform structure and architecture.
Check Point said it had launched a tool that exploits WhatsApp vulnerabilities and allows users to manipulate to raise awareness of the issue.
The cybersecurity company team showed how the tool could be used to change the text in the quoted messages, making it seem as if the person had written something they had not written.
said Vanunu « You can change what someone says entirely, you can manage each character in the quote, and the tool also allows attackers to change the way you select the sender of the message, which allows you to assign a comment to a different source, » .
At the beginning of 2018, Facebook’s email application had more than 1.5 billion users, with more than one billion collections and 65 billion messages sent every day.
